- Abstract
INTRODUCTION: Astronauts on deep space missions are at risk of sustaining fractures. 6 Mars analogue crew members taught themselves to perform uniplanar external fixation of an simulated open tibial shaft fracture using an open-access simulation-based training module that uses locally reproducible, high fidelity 3D printed bone models and a procedure checklist for self-assessment. METHODS: While a previously reported analysis of the data showed that confidence with self- performance of this simulation-based procedure improved significantly on all 8 measures evaluated, further analysis was needed to determine the practicality of having crew members undergo this type of training. We report the simulationbased training times and qualitative observations of the simulationbased training experience for the 6 subjects who taught themselves to perform uniplanar external fixation of an simulated open tibial shaft fracture. Each subject tracked and verified the successful completion of each step of the procedure checklist of another subject before performing the simulated procedure themselves. RESULTS: It took between 90-120 minutes for subjects to review the knowledge topics (which included watching a skills training video that showed the entire procedure) and between 32-45 minutes for subjects to complete one simulation-based procedure. The first subject opted to practice the procedure twice. All other subjects felt confident to perform the procedure once after assisting a fellow subject perform this procedure by observing and confirming the successful completion of each step of the procedure checklist. Subjects requested clarification of the medical terms in the procedure checklist. CONCLUSION: Mars analogue crew members can use open-source, high fidelity, 3D printed bone models and an open- access, self-assessed training module in under 4 hours to become confident and competent in performing a simulated external fixation procedure in an austere environment without access to specialist support from Mission Control. Using a procedure checklist reinforces surgical skills acquisition for crew members. A glossary of terms can be added to the training module to clarify medical terms for primary and back-up crew medical officers who have not completed formal medical training. LIMITS: The size of the Mars analogue crew limits the generalizability of our findings. KEYWORDS: "longduration space mission" "fracture - external fixation" "3D printing" Learning Objectives 1. The audience will learn about how Mars analogue crew members can use open-source, high fidelity, 3D printed bone models and an open-access, self-assessed training module to become confident and competent in performing a simulated external fixation procedure in an austere environment without access to specialist support from Mission Control. 2. The audience will learn about how using a procedure checklist during simulation-based training reinforces surgical skills acquisition for Mars analogue crew members with no prior medical training.
